How to Optimize your PC for Best Performance

Update Software & Drivers

The first step in optimizing your PC is checking if your system uses all the latest software. It includes your Windows version, installed apps & device drivers. Most of the time, a system running outdated software is less efficient & slower in performance.

Optimize Registry

The registry is the brain of your Windows system. It hosts all the program files that apps require for operating. However, over time as you install & uninstall a lot of programs, the registry gets filled up with redundant files.

Over time as this junk keeps accumulating, your registry becomes inefficient, causing a significant delay when apps are launched or in operation. Regularly cleaning this junk from your registry will optimize it for a responsive system.

Disable unnecessary start-up apps

Usually, many unwanted apps load automatically during Windows startup. It causes unnecessary memory consumption resulting in delayed boot times. You can disable these apps so that they can start only when you launch the app & not along with Windows.

It frees up vital resources during the startup time and reserves it only for priority apps.

Defragment hard-drives

With time, hard disks start fragmenting many files when storing them. This phenomenon can cause a significant delay in fetching the required files for launching an app. It happens because all the required data is spread across different sectors on the disk, and gathering them at once takes time.

Regularly defragmenting your disks will help your system to collect & store all similar files in nearby locations and reduce app launch times.

Remove Bloatware & Unnecessary Apps Running In The Background

Many times Windows or other useful apps may be used as vehicles to deliver bloatware to your system. These apps eat away your memory in the background and prevent important apps from accessing vital resources to function smoothly.

Identifying & removing bloatware & unnecessary apps can greatly improve your system performance.

Remove Malware

Your system might be infected with malware hidden deep within your files. Malware uses up resources on your system to further infect other users in your network.

Spyware or ransomware are some types of malware that eat into your resources, memory & hard disk to perform tasks like mining cryptocurrency or sending out phishing emails & more.

Scanning your system for malware & taking immediate action against them is key in maintaining your system in optimum condition.

Benefits of PC Cleaner Tools

Optimizing Windows at regular intervals is crucial in keeping your system fast & responsive. However, it is difficult to manually perform all these tasks individually. That’s why many usually skip these tasks in our daily work routines.

But, not optimizing your system can prove to be a costly mistake in the long run. To get over this, you can use a PC Cleaner tool. A PC Cleaner will help you optimize all key areas of your PC in a single window with the least input.
